Abstract
A retropsepctive study compared 2 child populations one with a significant measles vaccination rate and the other without such protection. Questionnaires physical examinations and antibody titers were used to determine the incidence of measles in the 2 groups. Findings demonstrated that measles incidence was significantly lower in the vaccinated group but also within unvaccinated children living in the same community. This significant level of protection was established within 3 years at a low overall vaccination rate performed by medical auxiliaries. Longer term effects of artificial immunity require further study. Of the 774 children included in this study 447 were from village a and 327 from village b. In order to establish a basis for comparing the 2 populatons the age and sex distribution health assessment arm circumference and weights were cross-tabulated. None of these variables suggest any significant difference between the 2 communities.
